摘要(Abstract)：

根据测井、岩心及分析化验资料,在等时地层格架基础上,结合老君庙油田古近系M油组区域沉积背景、岩石学、重矿物、粒度分析、沉积构造及砂体形态等,分析冲积扇识别标志,研究沉积相、沉积微相类型,刻画沉积微相展布规律,建立老君庙油田M油组冲积扇沉积模式。结果表明:M油组具备干旱气候条件下冲积扇沉积特征,主要发育冲积扇扇根外缘和扇中,扇根外缘发育片流带和漫洪带,扇中发育辫流带和漫流带。沉积微相平面分布样式一种为扇根外缘连片的片流带和离散的漫洪带拼接样式(M_3砂组),另一种为条带状辫流水道和透镜状漫流带相间拼接样式(M_2和M_1砂组)。整个M油组自下而上表现为冲积扇不断退积。研究区沉积相主要受控于构造运动、气候条件和古地形。
